The patient population for this study will have AML and will fall into a poor risk category. This means they have persistent leukemia after induction therapy, they relapse within two years of achieving complete remission with induction therapy, or they have certain poor risk features at diagnosis. The AML cells will also be positive for c-kit (a stem cell factor receptor), which is involved in cancer cell growth. Nilotinib is a drug that blocks the effects of c-kit. Using this drug in combination with chemotherapy may improve ability of the chemotherapy drugs to kill leukemia cells. This may then increase the chances of the leukemia going into complete remission.
